Charles & Sons Remodeling - Washington DC's Certified HVAC Services

High energy costs are a common concern with older systems in our climate. We specialize in right-sizing and installing modern, energy-efficient systems like ductless mini-splits, which offer zoned cooling and heating to avoid wasting energy in unused rooms. We can assess your current setup, identify air leaks or inefficiencies, and recommend a solution—whether it's a full replacement, a strategic repair, or adding a high-efficiency model—to help reduce your monthly bills and improve comfort.

Navien tankless water heaters provide an on-demand supply of hot water while using less energy than a traditional tank model, which constantly heats and reheats water. For DC homes, this means consistent hot water for households of any size and lower utility costs. Our team handles professional installation and repair, ensuring the unit is correctly sized and integrated into your home's plumbing for optimal, long-term performance and efficiency.

Regular maintenance is key to preventing costly breakdowns, especially during DC's hot summers and cold winters. Our maintenance service includes cleaning critical components, checking refrigerant levels, inspecting electrical connections, and calibrating your thermostat. This proactive care helps your system run more efficiently, extends its lifespan, maintains good indoor air quality, and can often catch small issues before they become major, expensive repairs.
